Warming apparatus for use during sleep

Abstract

A warming apparatus for use during sleep includes at least one of a temperature-up timer circuit for raising a temperature of an electric heater by an amount in the range of 2° C. to 6° C. for a predetermined time and thereafter restoring the temperature of the electric heater to a preset ordinary temperature, and a temperature-dowm timer circuit for lowering the temperature of the electric heater by an amount in the range of 2° C. to 6° C. for a predetermined time and thereafter restoring the temperature of the electric heater to the preset ordinary temperature, each of the temperature-up timer circuit and the temperature-down timer circuit being actuated while the warming apparatus is in operation.

We claim: 
     
       1. A warming apparatus for use during sleep comprising: an electric heater;   temperature setting means for presetting a temperature of said electric heater; and   a control circuit for controlling an electric current flow through said electric heater to maintain the temperature of said electric heater at the temperature preset by said temperature setting means,   said control circuit including a temperature-down timer circuit and means to actuate said timer circuit while said warming apparatus is in operation, to cause the temperature of said electric heater to become lower than the temperature preset by said temperature setting means by an amount in the range from 2° C. to 6° C. for a predetermined time period and thereafter restoring the temperature of said electric heater to the preset temperature.   
     
     
       2. A warming apparatus according to claim 1, further comprising a push button switch for actuating said temperature-down timer circuit. 
     
     
       3. A warming apparatus for use during sleep comprising: an electric heater;   temperature setting means for presetting a temperature of said electric heater; and   a control circuit for controlling an electric current flow through said electric heater to maintain the temperature of said electric heater at the temperature preset by said temperature setting means,   said control circuit including a temperature-up timer circuit and means to actuate said timer circuit while said warming apparatus is in operation, to cause the temperature of said electric heater to become higher than the temperature preset by said temperature setting means by an amount in the range from 2° C. to 6° C. for a predetermined time period and thereafter restoring the temperature of said electric heater to the preset temperature.   
     
     
       4. A warming apparatus according to claim 3, further comprising a push button switch for actuating said temperature-up timer circuit.
